In this study, we document pre-service teachers' (PSTs) opportunities to learn about planning for equitable and ambitious instruction during clinical placements. We also test whether these opportunities vary by the level of participants' perceived congruence between the vision of science teaching supported in their university coursework and the…

Agency has been used as a lens to focus on how educators learn through pedagogical risk-taking, advocacy for curricular reform, and resisting policies that are not focused on the needs of students. We explored the role of agency as 65 preservice science teachers created learning opportunities for themselves during their clinical placements.…

Rehearsal is an increasingly important teacher education pedagogy. We explore how 3 science teacher educators thought about and used pauses within rehearsals to support secondary science teacher candidates in learning to facilitate sense-making discussions. Video data indicated that the most common purposes for pausing a rehearsal were to provide…

In this article, we summarize more than a decade of work on high-leverage practices being used in the context of science teacher preparation. We describe the challenges and insights that ultimately resulted in more robust practices, a diversified suite of tools to support these practices, expanded knowledge of our own teacher education pedagogies,…

The ideas students bring to class and their perspectives on what is happening in the classroom change constantly. Keeping track of these changes is useful for adapting lessons, nurturing student self-reflection, increasing student ownership of learning, and building a teaching practice responsive to learners' needs. In this article, the authors…

Instructional tasks are key features of classroom practice, but little is known about how different components of tasks--such as selecting or designing tasks for a lesson, launching, and implementing them with students--shape the conditions for students' intellectual engagement in science classrooms. Employing a qualitative multiple case study…

This study examines the ways in which teachers provide students with written scaffolds in assessment tasks and the impact of these on students' abilities to demonstrate a core disciplinary proficiency--constructing evidence-based explanations. Data include 76 assessment tasks designed by 33 science teachers and 707 samples of student work. We…

Current theories of novice teacher learning have not accounted for the varied influences of pedagogical training, subject matter knowledge, tools, identity, and institutional context(s) on the development of classroom practice. We examined how 26 beginning secondary science teachers developed instructional repertoires as they participated in two…

Recent calls for teacher preparation to become more grounded in practice prompt the questions: Which practices? and perhaps more fundamentally, what counts as a model of instruction worth learning for a new professional--i.e., the beginner's repertoire? In this report, we argue the following: If a defined set of subject-specific high-leverage…

This article presents a model of collaborative inquiry for groups of science teachers who want to systematically improve their practice through analyses of student work. The five-phase APEX[superscript ST] (Advancing High-Leverage Practices by Examining Student Thinking) model is appropriate for students of all achievement levels. It focuses on…

One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

To test whether epistemically unproblematic ways of thinking and talking about science could be transformed during preservice teacher training, we designed a system of learning activities based on a set of "heuristics for progressive disciplinary discourse" (HPDD). The HPDD outline six design principles of learning environments where the aim is to…

Background/Context: The collegial analysis of student work artifacts has been effective in advancing the practice of experienced teachers; however, the use of such strategies as a centerpiece for induction has not been explored, nor has the development of tool systems to support such activity with novices. Purpose/Objective: We tested the…

Even though science teachers and other stakeholders all want students to be instructed in the most effective way possible, discussions about what that way might be are seldom productive. What the author has found in these conversations is that, despite a number of shared goals for student learning that participants bring to the table and despite…

In this article, the author distinguishes between traditional talk and reform talk. These two forms of approaches are often used in discussions concerning reforms in science instruction. Traditional talk focuses on student acquisition of scientific facts, concepts, principles, and skills while reform talk emphasizes that teachers must challenge…
